The Mini Serial Servo Controller (MiniSSC) was a PC controlled servo driver
board developed and manufactured by Scott Edwards Electronics,
Inc. It is no longer available, but many devices (e.g., the Maestro) support its protocol.

VSA Hobbyist and Professional can control 128 servos or
motors. These 128 devices do not need to correspond to
addresses 0-127, but can be mapped to other addresses. Simiarly, VSA Ultimate can control 256 devices.

VSA uses "frames" as time units.
Each frame has a minimum 33mS duration, so VSA can issue a complete set of servo commands 30 times a
second. This means that you can command servos to new a new position 30
times a second. The frame rate can be adjusted to be as slow as 5 frames
per second.

Currently, there are no updates
available for VSA v1.0, v2.0, v3.X, or v4.X. If you registered online,
you will automatically be notified of updates. If you
purchased VSA through a third-party, please
register
here. Updates are only included for the version you licensed (for example, VSA v4.0 useres will receive updates to VSA v4.1, but not VSA v5.0).

Yes, servo/motor positions can be
entered with a properly configured joystick. As you move
the joystick, the "virtual servo" follows the
action. Click here for more
information on how the virtual servo works.

The
K108A serial relay controller is an 8 channel relay
input/output module. According to the manufacturer, the
K108A can switch loads of 110V at 5A. The K108A can be
used with VSA and the RAPU v5.0 running at 9600bps.

Any board which uses the standard
D0-D7 binary outputs of the parallel port will be compatible
with VSA (see the VSA help file for more details). VSA
also strobes the nStrobe line during the write output. The
K74 Parallel Port Relay Board is an example of a
VSA-compatible parallel port relay card.

The Track Adjusment applies a linear mapping to all device positions. For example, let's say you want to convert from MiniSSC positions (0-254) to Parallax positions (250-1250). Thus, we want to provide a mapping between the two ranges. Track adjust applies the equation y = m*x + b, where y is the new position, m is the scale, x is the old position, and b is the offset. We must solve for m and b to use track adjust:

y0 = m * x0 + b => 250 = m * 0 + b => b = 250

y1 = m * x1 + b => 1250 = m * 254 + 250 => m = 3.937

So use scale = 393% and offset = 250 to convert from minissc to parallax. Note, you will need to assign the channel as a "Parallax Servo" first and set "Update Settings" to false.

There are many audio programs which can be used to create 7.1 audio files. For example, the freely available Windows Media Mono to Multichannel Wave Combiner can be used to create multiple channel audio files. Details on how to obtain and use it be found here. The required binary can be downloaded from the Microsoft website or here.

VSA can playback many video file formats, however some may not contain sufficient timing information to produce the best results. In particular, variable bit rate (VBR) video and audio should be avoided. For the best results, we recommend using either raw RGB or XVid AVIs.

Many software programs can be used to create your video content. Then, an editing program, such as VirtualDub, can be used to re-encode the content.
